“Mineral deposit model”, “deposit modelling” are the terms commonly
used, although imprecise. This is often identified as the application of
computerized methods to the elaboration and presentation of geological
information, in particular for the mining design. Deposit modelling is
the mode of presentation of deposit features, which in the meaning of
the authors of such presentation, describes the deposit features between
the points of observations as best as possible. Deposit modelling has a
long history (XVI-XVII centuries), however such a term was not used.
Varied methods of cartographic presentation of deposits and their
features were proposed. The progress in the presentation of the deposit
in space using isolines maps has led to the separation of methods of
deposits geometrisation. Over time, a simple mathematical statistics
method was used to describe the deposit parameters, followed by
geostatistical methods. Some of them were however not commonly used as
too troublesome. The computer based approach to the presentation of
geological data has an unquestionable value but is accompanied by the
possibility of inappropriate formalized and erroneous interpretations
and a presentation as to whether the basic rules of geological knowledge
were neglected. Deposits modeling is a conceptual task and cannot be
fully automated.
